ADSKAILab/floora-1.7b
FLOORA-1.7b by Autodesk Research is a 1.7 billion parameter autoregressive causal language model, fine-tuned from Qwen3-1.7B, specifically designed for architectural floor-plan generation. It excels at creating structured multifamily residential layouts from building metadata and massing geometry, outputting a compact, deterministically parseable architectural Domain-Specific Language (DSL). This model is optimized for rapid conceptual design and exploration within the Architecture, Engineering, and Construction (AEC) domain, offering a unique solution for automated floor-plan generation.

FLOORA-1.7b: Domain-Specific LLM for Architectural Floor-Plan Generation
FLOORA-1.7b, developed by Autodesk Research, is a specialized 1.7 billion parameter language model (fine-tuned from Qwen3-1.7B) focused on generating structured multifamily residential floor plans. Unlike general-purpose LLMs, FLOORA operates on a custom, compact architectural Domain-Specific Language (DSL) that is token-efficient, human-readable, and deterministically parseable, significantly reducing the data size compared to formats like IFC.
Key Capabilities
- Structured Floor-Plan Generation: Autoregressively generates labeled floor-plan polygons for living units, corridors, and vertical circulation cores from architectural prompts.
- Domain-Specific Language (DSL): Utilizes a custom DSL for outputs, enabling deterministic parsing, validation, normalization, rendering, and conversion into geometric floor plans.
- Human-Aligned Design: Incorporates architect-edited supervised fine-tuning and reinforcement learning with learned architect preferences and verifiable geometric/functional rewards.
- Efficient Parameterization: Although nominally 1.7B parameters, vocabulary resizing reduces its effective parameter count, enhancing efficiency for its specialized task.
Good For
- Rapid Conceptual Design: Ideal for quick generation and exploration of multifamily residential layouts.
- Automated Layout Exploration: Supports automated design exploration and architect review workflows.
- Architectural Design Research: Useful for research in structured AEC generation and domain-specific language models for engineering.
- Geometry-Aware Design Optimization: Facilitates design optimization through its structured and verifiable outputs.
FLOORA-1.7b is intended for conceptual proposals and design exploration, not as a replacement for professional architectural judgment or for generating construction-ready documents. Its specialization in multifamily residential layouts means performance may vary on highly irregular or out-of-scope geometries.
